Specification of Letters Patent.

Patented June 6, 1916.

Application 1ed December 24, 1909. Serial No. 534,796.

To all whom t may concern.'

'itiinoifi' that OLIVER M. EDWARDS, a citizen of the United States, residing in the city of Syracuse, county of Onondaga, State of New York, have invented certain new and useful Improvements in Windows, of which the following is a full, clear, and exact description, reference being had to the drawings 4accompanying the same.

yThe invention relates generally to double windows, that is, windows where one sash is mounted in front of or opposite another sash and both have to be moved to open the window, and moreJ particularly, with that class of double windows whereeach sash moves independently of the other and each is supplied with independent locking or sash holding devices.

One object of the invention is to provide a window in which the two opposite independently operable sashes are arranged in close proximity to one another and the holding devices on one sash do not interfere with the operation of the other sash and the sashes are moved transversely in the frame in opposite directions by the action of the holding devices thereon.

Another object is to provide a window in which oppositely arranged sashes are provided with holding devices adapted to en* gage with means attached to the frame and which is arranged between the sashes to force them into close contact with opposite portions of the guideway in which the sashes are mounted to move in opening and closing the window.

Another object is to provide a windo'w having two oppositely arranged independently movable sashes, each of which is provided with combined sash tightening land locking devices, mounted within a comparatively small thickness of frame.

Other objects will appear from the descriptions hereinafter given; and the invention consists in the combinations of parts or devices hereinafter set forth and particularly pointed out in the claims hereunto annexed which form a part of this specification. y

Figure 1 illustrates in front elevation portions of a frame and oppositely arranged sashes with portions of the front sash broken away to more clearly illustrate the relations of the sashes and attached parts one to the other. Fig. 2 illustrates that which is shown on line 2--2Y of Fig. 1 when looking from the right toward the left. Fig. 3 illustrates 1n cross section the relationsof the diEer-ent parts seen on line 3 3 of Fig. l near the top of the right hand portion thereof and also on line 3-3 near the bottom of the left hand portion of said figure. Fig. 4 illustrates in plan view a detail in the construction Vof the lower holding devices with one part separated from the other for the purposes of illustrating the manner of assembling such'holding devices with the sashes.'

Like letters of reference, wherever they occur, indicate corresponding parts of the several figures of the drawings.

A represents the frame in which the sashes are mounted and are free to move transversely therein to a limited extent and also in opening and closing the window and B B represent the oppositely arranged sashes.

A represents the guideway formed in the frame which receives the sashes, which are preferably separated by any desirable means, as a, which means, as shown, is attached to the frame in any desirable manner. The sashes B B, as shown, are formed from sheet metal and are comparatively thin and consequently occupy small space in the frame, each sash having exterior and interior thicknesses of metal arranged with spaces between such thicknesses in which portions of the holding means, as for instance those secured to the lower' portions of the sashes, are mounted.

These holding devices, as D, are of the preferred form and each is provided with a holding or locking detent, as d, which is preferably formed integral with one part of a divided or two part shaft, as ci. These shafts, as d', are preferably formed in two parts, as cl2 and (Z3, Fig. 4f, which parts are adapted to engage with one another and be received by a sleeve, as e, and operate as a single shaft. `lThese shafts, as CZ', are mounted'in bearings preferably formed, one on a base plate or casing, as c, and the other preff erably in a supplemental casing, as c', 'so as to partially turn'therein and each shaft has attached thereto a thumb or linger piece, as

7L, by which it may be partially rotated, the

thumb or finger piece extending through the casing or base plate and forming a portion of means for operating such divided shaft and locking or holding detent d, the other portion of such operating means being formed by the stationary or fixed part, as c', preferably formed integral with the base frame with suflicient force to move the sashV transversely in the guideway and bring it into close and intimate contact with the frame and thereby prevent the passage of currents of air, dust and rain between the sash and frame where the two are in contact.

These holding or locking devices, as D, are arranged with their holding or locking detente, as d, to move toward one another and force the sashes away from one another and into contact with opposite portions of the guidcway in which the sashes move, as will be seen upon reference to Figs. 2 and 3. The locking o-r holding detents, as d, on the oppositely arranged sashes point in opposite directions as seen in Fig. 2 and the free e l.ds thereof engage with suitable stops or vrecesses as al, a8 and m2, er", respectively, formed in the means, as a, attached to the frame of the window. The holding detents, as CZ, of the holding or locking devices mounted upon the lower portion of the sash B, engage with the stops or recesses a3 to hold the sash in the locked position when the window is closed and also engage with the recesses or stops, as a', to hold the sash B in the open position, the hooked end of such locking or holding' detent engaging with the stop, as a',

' to support the sash in the open position.

rihe 'hooked end of the locking or holding detents, as (l, of the devices mounted on the lower portion of the sash B engage with the stops or recesses, as a4, to hold the sash B locked in the closed position and the outer or free end of such detents engages with the stops or recesses a2, tohold such sash in thc open position. These locking or holding detents are forced by their springs connected therewith against the stops or recesses formed in the means, as o, attached-to the frame and by reason thereof the sashes are moved away from one another and held by the action of such springs in contact with the opposite portions of the guideway as before explained. The finger or thumb piece,

as It, attached to each of the rock shafts, as

d, forms a portion of operating means by which the locking or holdin@ detents, as al, are moved out of holding and locking pos1- 'tion the other portions of such means being' formed by the extending portion, as z', on the casing or base plate, as c, and the spring, as s, of the holding devices D.

These holding or locking devices, as D, are preferably made in two parts, one of which'parts, consisting of the casing c and attached parts is first attached to the sash end with an antifriction roller in any suitable manner and then the other part, consisting` as shown of the casing, as o, with the locking or holding detent, as d, and that part d2 of the rock shaft, as (Z, to which the detent is attached is mounted on the sash, the part of the shaft, as d2, being' inserted in a suitable opening in the casing o attached to the edge of the sash and the divided end portion of such shaft is inserted in aV sleeve as e and forced into place.V When the sash is made of thin sheet metal, as shown, that portion of the casing oV which receives the part of the shaft, as c 3, is insertedthrough an opening provided in the interior thickness of the metal which is of sufficient dimensions to receive the sleeve, as e, and that part of the casing c in which the part of the shaft, as d3, is mounted and then the flange portions of such casing are secured to the sash as' shown or .in any other desired manner. This opening in the sash is preferably of less length than that of the sleeve and shaft mounted in the casing or base plate and the sleeve and its support is inserted in the opening in an endwise direction in a inanner well'known to mechanics. These holding` devices, as D, are preferably made rights and lofts so as to be applied to opposite edge portions of the sash, but they may be used as shown or separately but reversed on one side of the sash if desired, each operating` upon that portion of the sash to which it is attached as herein described. By this manner of constructing and assembling` the parts the holding devices are mounted interior-lyV of and firmly secured to the sash without materially weakening those portions of it to which the devices are attached.

The holding devices, as K, arranged at the upper portions of the sashes-when the sashes are in the closed position-by which such sashes are forced in opposite directions into contact with the guideway are secured to the means, as a, as shown, or are secured in. place in any other desired manner, there being as shown two independently operating parts, as la, 7c, for each holding device and each part is preferably provided at its free to bear against the sash. These parts, as 7c, 70, as shown, are pivotally mounted on the frame preferably within the means, as 0;, and each is provided with a spring, which tends to force the free end of such part in the direction to hold the sashes in the frame. rlhe parts, as 7a, are forced by the tension of the springs 7' against the sash B and away from the means, as a5, and the sash is forced against that portion of the guideway nearest the exterior of the structure where used. The parts, as are substantial duplicates of the parts, as 7c, but the tension of the springs, as j', of the parts, as le', tends to move the free ends of such parts against the sash B and move the sash away from the means, as c, and into contact with the guideway. These holding devices, as K, which bear against the sashes B and B are always in bearing or holding action and the holding force is the same when the sash is being moved as when stationary. The use of the antifriction rollers lessens the frictionalcontact of such devices upon the sashes when the same are moved for opening or closing the window.

When the window is to be opened the operator moves the thumb or finger pieces, as h, upwardly, thereby moving the holding or locking detents out of holding and locking positions and when this is done, he applies suiiicient force to such operating means to raise the sash B into the desired position, when he permits one of the locking detents and attached linger pieces to be released to engage with a stop or recess, as a2, whereby the sash is firmly held in that position. The operation is repeated with the holding devices on the sash B, one of the locking or holding detents engaging with a stop or recess, as a', formed on the means, as a. Each of the sashes is movable independently o f the other and each of the holdas here shown.

Constructing the rock-shaft, as .Z, in two parts as shown and mounting the principal movable parts of the holding devices interiorly of the sashes, economizes space and also permits of such holding devices to be firmly secured in place without materially weakening the sashes, in fact the mounting of these two part holding devices in metal sashes as shown strengthens and stiifens the sashes instead of weakening them.

IVhat I have herein shown and described will naturally suggest to others skilled in this art other specific forms of this invention and also modifications in the construction and arrangements of the parts wherein substantially the same work is accomplished by essentially the same means having the same mode of operation as in the present case, and, consequently, I do not wish to limit my invention to the specific form herein shown, but desire to include all forms and modifications which embody the spirit of my invention as herein set forth.

What I claim as new is 1. The combination with a window frame, of two sashes mounted therein side by side, and designed to have independent sliding movement, and to have lateral movement, means projecting from the bottom walls of the sash guideways in said frame and eX- tending in between the two sashes, a springpressed detent projecting from the front face of the rear sash and engaging said means, and a spring-pressed detent projecting from the rear face of the front sash and engaging said means, the cooperation between said detents and said means tending to hold the rear sash against the rear window stop, and the-front sash against the front window stop, substantially as described.

2. rIhe combination of awindow? frame having sash guideways, of two sashes mounted therein side by side and designed to slide vertically in the guideways and to move laterally therein, engaging members projecting from the bottom walls of the guideways and extending in between the two sashes, lspring-pressed detents projecting from the front face of the lower part of the rear sash and coperating with said engaging members and from the rear face of the lower spring-pressed devices cooperating with said engaging members, and additional springpressed devices cooperating with said engaging members and the sashes, substantially as and for the purpose specified.

3. The combination with a window frame having guideways therein, of two sashes arranged side by side, strips extending from the bottom walls of the sash guideways and projecting in between the sashes, said strips having stop surfaces in opposite faces thereof, detents at the lower corners of each sash, a spring associated with each detent for forcing the same into engagement with the adjacent strip, manual means associated with each detent for withdrawing the same from engagement with the adjacent strip, two additional holding devices pivotally mounted in the upper part of each strip, and a spring associated with each additional holding device, the spring associated with one of said additional devices tending to force the free end of the latter into engagement with one of the sashes, and the spring associated with the other holding device tending to force the free end of the latter into engagement with the other sash, substantially as and for the purpose set forth.

4. The combination with a window frame, of two sashes mounted therein side by side and designed to have independent sliding movement, and to move laterally, a strip projecting from the bottom wall of each sash guideway and extending in between the two sashes, and a pair of holding devices mounted in said strip, and means associated therewith for yieldingly pressing engaging parts thereof in opposite directions and in engagement with the respective sashes for forcing them, respectively, against the front and rear walls of the sash guideways, substantially as and for the 'purpose described.
